NOTE: For data before 2000, the 1977 Office of Management and Budget (OMB) Standards for Data on Race and Ethnicity were used to classify persons into one of the following four race groups: White, Black, American Indian or Alaska Native, or Asian or Pacific Islander. The revised 1997 OMB Standards were used for data from 2000 onward. Under these standards, persons could select one or more of five racial groups: White, Black or African American, American Indian or Alaska Native, Asian, or Native Hawaiian or Other Pacific Islander. Those reporting more than one race were classified as “Two or more races." The race groups indicated for 2000 and later years represent individuals who reported that race alone. Data from 2000 onward are not directly comparable with data from earlier years. Data on race and Hispanic origin are collected separately. Persons of Hispanic origin may be of any race.
